Camera Lens News No. 18
Almost 3 million more Carl Zeiss lenses in 2002
The demand for high quality lenses from Carl Zeiss keeps growing. Almost 3 million camera lenses have been supplied to worldwide markets in the Carl Zeiss fiscal year of 2001/2002 ending September 30, 2002. This is the highest number ever delivered in a single year. The driving force behind this development is the rapid growth of the digital still camera market. The number of Carl Zeiss lenses delivered to the digital video market has also increased significantly. In a logical pairing of leaders in their respective fields, Carl Zeiss, with its unmatched optical expertise, has joined with Sony, a very successful global play-
er in both the still and video digital consumer camera markets. Sony is a technology leader in key components for digital cameras, like imaging chips, miniature components and circuits, and compact power supplies with high stamina. Sony has achieved commanding positions in many digital still camera markets around the world and is the undisputed leader in the digital video camcorder business. Since 1997 Sony has equipped its top digital still and digital video camera models with high-performance lenses by Carl Zeiss. These cameras are very successful, gaining market share.

Contax TVS Digital

In the Contax camera world, the TVS label denotes high quality compact lens shutter (point & shoot) cameras made of particularly high value materials, equipped with a Carl Zeiss T* lens of the Vario-Sonnar type (hence the VS in the camera name). Photokina 2002 saw the introduction of the first digital Contax TVS. It is a 5-megapixel-camera with the now familiar titanium housing. The lens is a very compact Carl Zeiss Vario-Sonnar T* 2.8 4.8/7.3 21.9 unit with 6 elements in 6 groups. Coverage of this autofocus lens is equivalent to a 35105 mm zoom on a 35 mm camera. 4x digital zooming extends the tele zoom range to 420 mm (in 35 mm terms). Normal close focusing goes to 0.6 m, but a special macro-function enables close-ups in the 0.15 to 0.6 m range. The Contax TVS Digital will become available soon at a very attractive price of 999 ($ 999). For more information on this camera, please visit: www.yashica.de www.contaxcameras.com The design criteria given to Carl Zeiss were the following: moderate speed (f/4.5 to f/8); a moderate zoom factor (2.5 x) and moderate image angles (77 to 35 degrees diagonally). The result is the Vario-Tessar T* 4,5 8/autofocus lens in the Yashica T zoom camera, with close focusing to 0.5 m. While offering the useful wideangle of a 28 mm lens, Carl Zeiss kept the lens compact and highly affordable. The resulting design of the first Vario-Tessar

Vario-Tessar A new compact zoom lens by Carl Zeiss
Vario-Tessar is a new zoom lens concept by Carl Zeiss which enables quite small lenses as required for current compact, lens-shutter (point & shoot) camera designs. Market pressures require these cameras to be rather flat regardless of the image receiver used, be it 35 mm film, APS film, or a digital imager. The new Yashica T zoom, introduced at Photokina 2002 in Cologne, is the first camera to be equipped with a Carl Zeiss Vario-Tessar lens, in the 100th anniversary year of the original Zeiss Tessar patent from 1902. The new Yashica camera with the first Vario-Tessar T* lens has met the expectations of the market extremely well. The photo trade ordered this camera at Kyoceras Photokina booth in outstandingly high quantities for the Christmas season. Kyocera has decided to double the production capacity to keep up with the demand from the market. For more information on this camera, please visit: 100 years of Tessar www.yashica.de from high quality optical glass. All glass types used are modern ECO-versions which are free of lead and arsenic. The Vario-Tessar T*4,5 8/lens in the Yashica T zoom camera offers autofocus and close range focusing up to 0.5 m.

Tele-Apotessar T* 4/400 lens for Contax N autofocus system
Fast, yet handy apochromatic telephoto lenses have become indispensable optics for both sports and wildlife photographers. For the Contax N SLR system, Carl Zeiss has designed an all new autofocus lens, Tele-Apotessar T* 4/400. It is relatively fast and thanks to its great balance on the N-series Contax autofocus cameras, can be hand-held. It will produce images of stunning sharpness and brilliance over the entire frame, even wide open. Its resolution of fine detail impresses even the most demanding photographers, along with very low distortion. This high performance is virtually constant over the entire focusing range from infinity to the close-up limit of 2.9 m, giving a minimum field size of 150 mm x 224 mm. Utilizing the latest in optical glass technology and precision manufacturing, the Tele-Apotessar T* 4/400 lens marks a summit in the development of Carl Zeiss Tele-Apotessar lens designs. It consists of 8 lens elements in 6 groups and covers an angular field of 6.2 degrees. Its performance challenges the quality of the best color films to their limits. The electric drive diaphragm of the Tele-Apotessar lens offers an aperture range of f/4 to f/32. The length of the lens is 292 mm, the diameter is 120 mm, its weight 3580 g, and it uses inexpensive 46 mm diameter filters in a convenient filter drawer. The lens comes with a rotating tripod collar. At the close focusing limit of 2.9 m a magnification of 1:6,2 (0.16 x) is reached. The resulting object field covered then is 150 mm x 224 mm. Tele-Apotessar T* 4/400 lens Preferred fields of application are: sports, wildlife, photojournalism, fashion, advertising, portraits from a distance, photos with very shallow depth of field, documentation of inaccessible objects and actions.

Carl Zeiss Sharp Max Maximising the sharpness of B-4-Mount lenses on 2/3rd inch High Definition cameras
The new Carl Zeiss Sharp Max precision collimation device is designed to provide accurate and consistent backfocus for the entire DigiPrime lens series, thus maximising the sharpness actually achieved in camera.
Zeiss factory in Oberkochen has since been ramped up to cope with the orders which keep coming in beyond expectations. Carl Zeiss has ordered the materials for additional production batches quite ahead of schedule. A growing number of digital cine productions plan to use Carl Zeiss ting time short. www.digiprimes.com DigiPrime lenses and
DigiPrimes lenses are the first set of primary lenses available in 5 mm (T1.9), 7 mm (T1.6), 10 mm (T1.6), 14 mm (T1.6), 20 mm (T1.6) and 40 mm (T1.6) to utilize the full potential of the finest 2/3 High Definition cameras. The Sharp Max is a compact device, not much larger than a lens, designed to go anywhere DigiPrime lenses go. After using it for the first time, Director of Photography Mike Spodnik, SOC commented, The new Sharp Max alignment device lets me make sure my back focus is properly set. It cuts quite a bit of time, so I can change prime lenses as often as I like within a minute or a minute and a half. It took me about 30 seconds to learn to use it. The fact that its field useable, small and self-contained makes it too good a device to leave out of any lens package. With the Carl Zeiss Sharp Max, backfocus adjustment is accomplished quickly and easily. With the Sharp Max attached to the front of the DigiPrime lens mounted on the shooting camera, the operator sets the lens focus scale to the mechanical infinity limit and adjusts the back-focus ring for the best visual resolution of the Siemens star image in the camera viewfinder or on the monitor. Finally the operator locks the backfocus ring, removes the Sharp Max from the lens, and returns to normal operation. The full procedure usually takes less than 30 seconds.

The new Carl Zeiss SharpMaxTM precision collimation device
The Carl Zeiss Sharp Max sports a rugged housing of anodized aluminum and has been constructed to match the quality of high precision Carl Zeiss camera lenses. Its athermal design features specially selected materials such as Invarstahl to avoid thermal expansion of critical components which would throw the optical adjustment out of precise alignment. The front of the unit is equipped with a clamping mount for Carl Zeiss DigiPrime lenses (which feature a uniform 95 mm front diameter). The mount is interchangeable, thus allowing Sharp Max to be compatible with other lenses featuring larger or smaller front diameters.
